BAFFLE sno'rron son nor-WATER HEATERS.

Application filed April 22, 1924. Serial No. 708,308.

To all whom it may concern:

Be it known that I, WALTER I-I. MILLER, a citizen of the United States,leSldlIlg at the combustion chamber into the flue, preventing the wasteof heat, by providing a bafile, adapted to cut oil the direct passage 01combustion gases to the flue, and cause them to take a more circuitouspath, in order that a maximum amount of heat may be transmitted to thewater or other medium to be heated in the heater structure.

Another object of the invention resides in providing a battle attachmentfor Arcola hot water heaters of special construction, adapted to besupported by the cross members of the section of the heater, forrestricting the passage to the flue, in order that the combustion gaseswill pass to the forward portion of the heater, and through the spacesbetween the cross members at the forward portions, to the flue passagein the top portion of the heater section, and finally to the flue, inorder that a maximum amount of heat will eflect and heat the sections ofthe heater, for heating the water.

In the drawing, forming-a part of this application Figure 1 is avertical transverse sectional view, through an Arcola type of hot waterheater, showing the invention applied thereto.

Figure 2 is a vertical longitudinal section, taken on the line 2-2 ofFigure 1.

Figure 3, is a horizontal sectional view, taken on the line 3--3 or"Figure 1.

Figure 4 is an enlarged detail perspective view, of one of the battleforming elements.

The well known type of Arcola heater now used in the art, includes aplurality of heater forming sections, indicated at 1, which formintermediate sections, there being a specially constructed frontsection, and rear section, the rear section being indicated at. 2, andprovided with a flue at the upper end thereof, as at 3, for thereception of the usual flue pipe, connected with a chimney. The centralor intermediate sections 1 of the heater are substantially rectangularin form, and cast in hollow inter-fitting sections, as

' illustrated. Each section is provided slightly below the top portion,with a cross member 4:, which is cast hollow and integral with the mainportion of the section, in order to provide for a water receiving space.In assemble-d relation, the cross members a, combine to form a fluepassage, which may be indicated, at 5, in the upper portion of theheater, which communicates with the flue opening 3, in the rear section2. It will be further noted that each of the sections 1 are providedwith integral inwardly extending flanges, such as indicated at 6, which,in assembled relation, are spaced from each other, in order to provide alarge heating surface,

within the combustion chamber of the heater.

The present invention is adapted to provide a battle for limiting thepassages between the cross arms 4 to the flue passage 5, by providing abaflie, indicated generally at 7 which includes the provision of aplurality of segmental bafile plates 8. Each batfie plate includes aplate section 9, provided on the bottom with a depending projection 10,and at one end with a lateral projection 11, of a width equal to thewidth of the projection 10, which is equal to the space between thecross arms 4 of the heater sections. One end and a side of the plateportion 9, are slightly inclined inwardly and downwardly, as indicatedat 12, for a purpose which will presently appear.

A pair of these plates 8 are mounted in aligned abutting relationbetween sections 1, of the heater, in a manner clearly illustrated inFigures 1 to. 3, the projections 11 from one end of each plateprojecting:

into the space between the flanges 6 of each of the intermediate heatersections. The ends of the plate sections 9 of each bafile plate abut inthe central portion of the heater, while the side edges of said plate'sections, abut the side edges of the adjacent plate sections, mountedin the next adjoining space between the heater sections, in order tocooperate and form a'baffie 1n the rear section of the heater, toprevent the combustion gases from passing upwardly and directly into theflue, without heating. the upper portion of the heater section, at theforward end thereof. The provision of this baffle section, Will causethe combustion gases to first pass upwardly, in the heater, and thenforwardly to the spaces between the cross members 4 at the forwardportion of the heater, and then Subsequently through the flue passage 5,in the top portion of the heater, to the flue pipe. This will cause theheat to circulate for a longer time within the heater, in order that agreater heating of the Water in the sections thereof, will result forobtaining the maximum benefit of the heat of the fire in the heater.

It will therefore be apparent that a novel form of baffle has beenprovided for hot Water heaters of the Well known type, adapted toprevent the direct passage of the gases to the flue, in order that fullbenefits from the heat will be obtained.

thickness equal to the combined thickness 01 said plate and rib, thefree end of said extension being bevelled and notched upon its underside.

In testimony whereof I afiix my signature.

WALTER H. MILLER.
